BLUELAN Compatible Mellanox MCP1650-V003E26 QSFP56 Direct Attach Cable, 200GBASE-CR4, InfiniBand, 30AWG, 3 Meter (MCP1650-V003E26-BL)

High-speed data centers and HPC clusters need reliable 200G interconnects without the cost and complexity of optical modules. This BLUELAN passive Direct Attach Cable (DAC) delivers exactly that: a 3-meter copper link that plugs directly into QSFP56 ports, supporting 200GBASE-CR4 and InfiniBand protocols. It eliminates the need for separate transceivers, reducing latency and power consumption while maintaining signal integrity over short distances.

Who is it for

Network engineers and system integrators deploying Mellanox switches, NICs, or servers in data centers, HPC environments, or enterprise racks. Ideal for top-of-rack to server connections where 200G throughput is required over short distances.
